Application Effects of Microwave Hesetor in the Resection of Soft Tissue Sarcoma of Thigh ( Over 10 cm in Diameter) / 中国微创外科杂志

ABSTRACT

Objective To explore the effectiveness and feasibility of microwave Hesetor in resection of soft tissue sarcoma of deep thigh. Methods From January 2009 to August 2014, 33 patients underwent tumor resection of soft tissue sarcoma of deep thigh (10-37 cm in diameter).The high frequency electroscalpel was used in 15 cases before December 2012 (electroscalpel group) whereas the microwave Hesetor was used in 18 cases after January 2013 ( microwave group) .The intraoperative blood loss, operation time, transfusion proportion, length of hospital stay and postoperative drainage volume were compared between the two groups. Results The intraoperative blood loss was significantly decreased in the microwave Hesetor group as compared with that in the electroscalpel group [(175.0 ±129.8) ml vs.(356.7 ±238.2) ml, t=-2.645, P=0.015].Three patients in the electroscalpel group were given blood transfusion of 200 ml, 400 ml and 400 ml, respectively, due to a massive intraoperative hemorrhage, while none in the microwave group required blood transfusion.There was no statistical difference between the two groups regarding to the operation time, length of hospital stay and postoperative drainage volume (P>0.05). Conclusion Microwave Hesetor is of great value in the resection of soft tissue sarcoma of thigh for significantly reducing intraoperative bleeding and obviating blood transfusion.
